I'm not sure I completely understand the question but I'll give it a shot:
> have no competences : I've got a buzzer which aims at producing a sound
what's a buzzer ? like a huge gameshow button ?

higher freuqncies are generally perceived as louder

square waves have rich harmonics = more high frequencies -> they will be per-
ceived as louder than a pure sine at the same level.

this might not work as expected, esp. since you'll require noticeable dynamic
